Automatic fuel saving method (favorites)

Today, I talked to people about the shift problem of the car. I got some tips and thought it was quite reasonable:
There are some oil-saving skills on the Internet for automatic vehicles, but there are still many places that I don't understand. I would like to thank you for your advice.

Question 1: Can I directly go to the D file from the empty or P file at startup? I used to step on the brakes and start again.
Question 2: Is it easy to switch to n when parking is fast? Is n correct or is n correct?
Question 3: Do I need to switch to N for temporary parking? Tired of standing on the brakes...
Question 4: Is it better to add half a box for fuel? I have a friend who drives a big car and adds 100 yuan of oil each time?

(1) the vehicle can be started only when the P and N blocks are used. The P block must be used to pick out the gear lever and stop the brakes. The use of N-gear start is when the vehicle is directly forward after the start, you can first turn on the power supply (without the engine), step on the brakes to pull the block to n-gear, and then ignition, after mounting to the D block, direct forward, this can avoid P block fire, need to pass through the R block, so that the gearbox through a reverse impact.
(Note: Generally, ignition is directly performed on the p-drive and the brakes are placed on the D-drive without any special impact on the speed control system. Unless the user needs to protect the gearbox with special precision .)

(2) generally, you do not need to press the shift button when switching between blocks N, D, and 3. you must press the shift button when mounting the gear from the 3 blocks to the next limit, you do not need to press the shift button to move from low to high. The buttons on the shift lever are also arranged incorrectly without shift buttons, such as Buick Excelle.

(3) During driving, N-shift slide should not be mounted. Because lubrication is required in the automatic transmission, when the gear is placed on n-block, the oil pump cannot be properly supplied for lubrication, this will increase the temperature of the internal component of the gearbox and cause complete damage! In addition, high-speed time-space sliding is also very dangerous, and it is not fuel-efficient! When the system slides to the stop at low speed, you can mount n blocks in advance, which has no effect.

(4) the automatic car cannot be pushed into the P block during driving, unless you do not want to get the car, when the driving direction changes (forward, backward, or backward) that is, when the forward or forward block is mounted to the reverse block, you must wait until the vehicle is stopped.

(5) At the end of the trip, the automatic vehicle must be turned off and put into the P block to extract the key. Many people are used to stopping and pushing P block to stop the vehicle and then pull the handbrake. Careful people will find this operation. After the flameout, the vehicle will usually move around and around due to uneven roads, at this time, the P-shift gearbox has a bite device and the variable speed gear bite, then the movement will cause a little impact on the variable speed gear. The correct method should be: after the car enters the parking position, it will step on the brakes to pull the gear lever to N blocks, pull the handbrake, release the foot brake, and then turn it off, and finally push the gear rod into P blocks. Of course, this is also the protection of gearbox excellence. It should be noted that the difference between P block and N block is that there is a gear in the p block, which is not only used for parking, but also helps the vehicle to brake, after stopping a vehicle, you must push the gear block to the P block. Do not place the gear on the N block and press the * handbrake to stop it. This is especially true for parking in a place with a slope.
(Note: When parking a car, you can step on the brakes, pull the handbrake, enter the P archive, stop, and release the brakes. It will not have a special impact on the speed control system. Unless the user needs to protect the gearbox with special precision .)

(6) In addition, there is still some debate about whether to use N or D blocks for automatic parking (such as a red light). In fact, it does not matter. N or D block are not wrong, temporarily stop and hold the brakes hanging on the D block does not damage the car, because the torque converter in the gearbox is equipped with a group of reaction wheels with one-way clutch, its function is to enlarge the torque from the engine crankshaft. It does not rotate at the engine idle speed. It only takes effect when the engine speed increases. So it doesn't matter if you step on the brakes or other red lights. It's okay if you hold the N block and pull the handbrake. The advantage is that you can move your right foot. You can apply a relatively rigid indicator: If you stop for more than half a minute, you can mount the n-shift handwheel. If the parking time is short, you can press the brakes. It is worth noting that this is the use of general automatic vehicles. When your vehicles have special requirements, you cannot follow this, for example, Buick, it is clearly emphasized in its use of the optical disc that it cannot be attached to N blocks during temporary parking, because it has the automatic skip block function. After you press the brakes for a few seconds, the gearbox automatically jumps to the neutral block.
